'''SysML''', or '''Systems Modeling Language''', is a [[___domain-specific modeling]] language for [[systems engineering]]. SysML was originally developed by an [[open source]] specification project, and includes an open source license for distribution and use. SysML is derived from, and is an extension of, [[Unified Modeling Language]] Version 2.1.

SysML is notable for the wide range of systems concepts it can model. In an automotive application, for example, the language can be used to specify mechanical objectives and constraints such as maximum acceleration, [[curb weight]], [[air conditioning]] performance, and interior cabin [[acoustical engineering|noise management]]. It can specify electrical parameters ranging from the [[FM radio]] [[tuning sensitivity]] to the [[real-time]] response of the [[antilock brake|anti-lock braking]] control electronics. It can specify and model the [[embedded software]] used to control the on-board automotive computers. Finally, it can model the factories used to build the car, as well as the interfaces between the organizations that work in the factory. SysML does not replace the simulation tools used to model specific subsystems, but rather provides the "glue" to model the interaction between subsystems.

The OMG is adapting and adopting a version of SysML which it calls [[OMG SysML]]. The OMG SysML Specification v. 1.0 is the final adopted specification, [http://www.omg.org/docs/ptc/06-05-04.pdf OMG document ptc/06-05-04], and is following the OMG technology adoption process.

SysML is notable for the wide range of systems concepts it can model. In an automotive application, for example, the language can be used to specify mechanical objectives and constraints such as maximum acceleration, [[curb weight]], [[air conditioning]] performance, and interior cabin [[acoustical engineering|noise management]]. It can specify electrical parameters ranging from the [[FM radio]] [[tuning sensitivity]] to the [[real-time]] response of the [[antilock brake|anti-lock braking]] control electronics. It can specify and model the [[embedded software]] used to control the on-board automotive computers. Finally, it can model the factories used to build the car, as well as the interfaces between the organizations that work in the factory.

A notable innovation of SysML over the [[Unified Modeling Language|UML]] is support for [[requirements modeling]]. During the design process, designers and users of specific sub-systems can communicate the design criteria using several alternative design formats including diagrams, tables, and tree structures. The requirements provide a checkable interface and documentation of the evolution of the system design over time.

== History ==

SysML does not replace the simulation tools used to model specific subsystems, but rather provides the "glue" to model the interaction between subsystems.

The language was developed to meet the requirements contained in the UML for Systems Engineering RFP (ad/2003-03-41).

The [[Object Management Group]] (OMG) is adapting and adopting a version of SysML which it calls [[OMG SysML]]. The OMG SysML Specification v. 1.0 is the final adopted specification, [http://www.omg.org/docs/ptc/06-05-04.pdf OMG document ptc/06-05-04], and is following the OMG technology adoption process. OMG SysML is sponsored by the OMG and [[INCOSE]]

SysML holds particular appeal for the [[aerospace|aerospace industry]]{{fact}} which designs products with highly optimized electrical, mechanical, and software sub-systems. In creating a standardized modeling language, it is hoped that the design tradeoffs can be better managed.
